caption_attribution_description: English: First Great Western Class 165 at Guildford Platform 8, with a service bound for Reading.
context_page_description: The North Downs Line is a passenger-train line connecting Reading, on the Great Western Main Line, to Redhill and Gatwick Airport, along the Brighton Main Line, linking many centres of population in that part of the North Downs which it traverses en route.
context_section_description: The main services on the line are provided by Great Western Railway using Class 165 and Class 166 Network Turbo diesel multiple units. Hourly semi-fast services run from Reading to Gatwick Airport and there is an hourly stopping service between Reading and Redhill. At Redhill the Gatwick Airport services reverse to head south along the Brighton Main Line. Until 1994, the stopping services continued to Tonbridge, but the line between Redhill and Tonbridge was electrified in 1993. Trains on this section are now operated (by Southern) as a shuttle service between Redhill and Tonbridge only.
  In 2020 the Class 165 trains are due to be replaced by Class 769 Flex four-carriage trains, once a number of station platforms have been extended.
  Additional services on the North Downs Line are provided by South Western Railway between Reading and Wokingham (trains to/from London Waterloo) and between Ash and Guildford (trains to/from Alton or Ascot). Southern operates services between Reigate and Redhill and onwards to London.
  There is also one train a day in each direction between Reading and Guildford, operated by CrossCountry. These trains run to and from Newcastle.
